IL-23 Inhibitors for Active Crohn's Disease
This study follows patients with moderate-to-severe Crohn's disease who are starting a newer type of biologic medication called IL-23 inhibitors (guselkumab or risankizumab). Researchers want to understand how well these drugs work in real-world clinical practice and compare their effectiveness to other treatments.
Guangzhou, GuangdongAges 18–75 - NCT07544784RecruitingPhase 2
AK104 plus radiation for colorectal cancer spread to liver
This study tests a new immunotherapy drug called AK104 combined with radiation therapy and standard chemotherapy for colorectal cancer that has spread to the liver. The goal is to see if adding AK104 and targeted radiation improves treatment outcomes compared to standard therapy alone.
ShanghaiAges 18 years+ - NCT07546097RecruitingPhase 4
Upadacitinib vs Steroids for Severe Ulcerative Colitis
This study compares a newer medication called upadacitinib to traditional steroids for treating acute severe ulcerative colitis (sudden worsening of UC with bloody diarrhea and urgent symptoms). The goal is to see which approach works better as a first treatment.
Ankang, ShaanxiAges 18–85 - NCT07544433Recruiting
Breathing Training to Help Reduce Acid Reflux
This study tests whether special diaphragm breathing exercises (using the muscle below your lungs that controls breathing) can reduce acid reflux symptoms. You'll learn and practice these exercises over time to see if they help your GERD without needing more medication.
Changhua, Changhua CountyAges 20–80 - NCT07549399RecruitingPhase 3
Radiation, Chemotherapy, and Immunotherapy for Rectal Cancer
This trial tests a combination of radiation, chemotherapy, and immunotherapy drugs before surgery for people with locally advanced rectal cancer. The goal is to shrink the tumor and improve outcomes for patients with higher-risk disease.
Guangzhou, GuangdongAges 18–75 - NCT07549724Recruiting
Assessment tools for swallowing problems from brain conditions
This study tests new ways to evaluate and measure swallowing difficulties caused by neurological conditions like stroke or Parkinson's disease. Participating helps researchers develop better tools to diagnose and monitor swallowing problems in patients with these conditions.
Venezia, ItalyAges 18–85 - NCT07549958RecruitingPhase 1
Gemcitabine with or without Pitavastatin for Advanced Pancreatic Cancer
This study tests whether adding pitavastatin (a cholesterol-lowering drug) to gemcitabine chemotherapy can help treat pancreatic cancer that cannot be surgically removed. You would join if your cancer hasn't grown worse after 2–4 rounds of gemcitabine.
Orange, CaliforniaAges 18 years+ - NCT07550023Recruiting
How Different Dietary Fats Affect Your Gut Health
This study examines how different types of dietary fats influence the bacteria in your gut and how your body processes nutrients. By participating, you'll help researchers understand the link between fat intake and digestive health in healthy adults.
GlasgowAges 20–50 - NCT07550673RecruitingPhase 4
Upadacitinib vs. Infliximab for Severe Ulcerative Colitis
This study compares two medications—upadacitinib and infliximab—as second-line treatments for acute severe ulcerative colitis (a serious flare of inflammatory bowel disease). The trial will help doctors understand which treatment works better when standard first-line therapy hasn't controlled the inflammation.
Ankang, ShaanxiAges 18–85 - NCT07543263Recruiting
AI-assisted ultrasound diagnosis for pancreatic cysts
This study uses artificial intelligence to help read endoscopic ultrasound images of pancreatic cysts. It aims to make diagnosis more accurate and could help guide treatment decisions.
Jinan, ShandongAges 18 years+ - NCT07550088RecruitingPhase 2
Combination therapy for colorectal cancer with liver tumors
This study tests a combination of three drugs for patients with colorectal cancer that has spread to the liver. The goal is to see if this combination can shrink tumors and help patients live longer.
La Jolla, CaliforniaAges 18 years+ - NCT07546565Recruiting
Bowel Prep Before Minimally Invasive Colon Cancer Surgery
This trial tests whether cleaning out your colon before surgery for early-stage colon cancer affects outcomes when surgeons use a minimally invasive (laparoscopic) approach. Researchers want to see if this prep step makes a difference in recovery and complications.
